Cam breakin Procedure

I just buttoned up my 318. Installed new cam, heads, lifters, springs, retainers, headers, etc.. I fired it up for about 10 seconds then shut it down. What I need to know is, what is the procedure to run it for breakin, and how long? Anything special, or just run it? I'm using proper type oil, additives, coatings, etc.. Thanks Mike
